Karapan sapi is a traditional bull racing festival on the Indonesian island of Madura. Every year from about July through October, local bulls are yoked to wooden skids and raced for 130 meters, similar to a chariot race. There are several of these races throughout the season, and there is a final trophy race held in Pamekasan. The bulls participating in the event are adorned with gold and other decorations, and the event may be accompanied by Gamelan music, food, and wagers on the outcome of the race. A depiction of the festival was featured on the reverse of the 100 rupiah coin for Indonesia from 1991 to 1998. An Indonesian stamp issued in 2009 also depicted the race, along with the Surabaya–Madura Bridge.
